Я нашел решение для этого. Это может сэкономить кому-то драгоценное время.
select EmployeeID,DOB,dates.date from emp_tb_eob_employeepersonal
cross join dbo.GetDays(Getdate(),Getdate()+7) as dates where weekofmonthnumber>0
and month(dates.date)=month(DOB) and day(dates.date)=day(DOB)
GO

Создайте перекрестное соединение с датами и проверьте сравнение месяца и дат.
